Hydrography

Lake Oron sits at an elevation of 353 meters (1,158 ft) above sea level. It is 24 kilometers (15 mi) long and 6.5 kilometers (4.0 mi) wide, with a surface area of 51.3 square kilometers (19.8 sq mi) and a maximum depth of 184 meters (604 ft). The western and eastern slopes of the lake are practically vertical, and 85 percent of the lake is of a depth greater than 100 meters (330 ft), while the northern part of the lake that connects to the Vitim River is more shallow, with depths up to 18 meters (59 ft). The presence of deep faults beneath Lake Oron strongly suggest that the lake has a tectonic origin, with a hydrological regime determined more by changes in precipitation than by glacier meltwater.^[1]
